Now I think I have the feel for the process: each action that is
called attempts, through automagic, to render the screen with it's
particular view file. If I use Ajax to call the particular action, and
use the 'update' option and specify a DOM item, then the action will
render it's view code inside of this DOM item.
Is this best practice? Should I be worried that I'm essentially
inserting one view inside of another?
I think I have it figured out now. Thanks for the help Mark, it helps
me a lot.
